To all whom t may concern,.-

Beit known that I, JUAN BoFILL OLIVERA, a citizen of the Republic ofCuba, and a resident of Matanzas, in the Provinceof Matanzas, Cuba, haveinvented anew and Improved Educational Device, of which the following isa full, clear, and exact description.

The purpose of my invention is to provide letters which are inpivotally-supported sections capable ot being brought together toproduce the full form otl a letter or of being separated or disarranged,so that they will necessarily have to be reassembled.

Another purpose of the invention is to provide a means whereby childrenmay be quickly and readi'ly'instructed as to the outlines of capital andsmall letters, Roman or in script, the letters, as stated, being inpivoted sections, and to provide in connection with the said pivotedsections ot a letter an outlined letter on the support, so that whenYthe sections have been moved promiscuously they can be assembled on theoutlined letterwhich serves as a guide, thus giving employment to theyoung student and impressing the character of the letter on the mind.

The invention consists in the novel con-l struction and combinationofthe several parts, as will be hereinafter fully set forth, and pointedout in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specilication, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a frame and blocks in the frame havingsectional letters produced thereon and an easel supporting the saidframe. Fig. 2 is a horizontal section taken through the frame and theblocks shown in Fig. 1. Fig. 3 is a perspective view of one of theblocks, illustrating one of the capital sectional letters thereondisarrauged. Fig. 4 is a view similar to Fig. 3, but showing the reverseside of the block shown in Fig. 3, whereon a small corresponding letteris produced and the sections adapted to formv ing the letters of thealphabet and their formation to a class. This frame is adaptedto receiveblocks C, corresponding in number to the number of letters in thealphabet. VEach block C is provided upon one face with separable capitalletters 10 and upon the other face with separable small letters 11, andsaid letters may be produced in block or Roman characters or in Italicsor in script.

The letters, no matter what their character may be, are made in sections12, the ends 13 of the said sections being beveled or straight, as maybe demanded in the formation of a complete letter after the sectionsofthe letter have been so separated that said sections in no manner showthe correct outlines of a letter, but which sections, when properlyassembled, portray the intended letter. Each section 12 of a letter ispivoted to a block C b v means of a pivot-pin 14, so located as toenable the sections to be conveniently manipulated when the sections areto be separated and to produce a perfect jointure when the sections areassembled. Each .block has an outline or an imprint 15 of the letter tobe formed produced thereon, and the sections of the sectional letterscorresponding to the said imprint or outline 15 are so pivoted that whensaid sections are properly assembled the connected sections of aletterwill cover the imprint, which is employed as a guide for the personlearning the formation of a letter.

The sections of the letters are usually made of thin metal; butcelluloid or other appropriate material may be used.

In Fig. 5 I have illustrated the sectional letters applied directly tothe pages of a book 16, the capital letters being on one page and thecorresponding' small letters upon the neXt page. This book is intendedfor the pupil, and the guiding outlines or imprints of the letters,although shown, may be omitted, and the pupil thus be compelled to relyupon his memory or idea of the formation ofthe letter demonstrated bythe instructor.

I desire it to be understood that numerals and characters may beproduced in the same manner as the letters described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In an educational device, a block, and a sectionalletter on the block, which letter is a fixture and is constructed insections independent of each other and pivotally sustained on the block,whereby the sections of the letter are capable of separation andassemblage. 2. In an educational device, a support having a characteroutlined thereon and a corresponding character constructed in sections,

which sections are pivota'lly mounted on the said outlne,the sectionalcharacter being a fixture on the support for the purposes described.

3. In an educational device, a block having an outline of a capitalletter on one face and an outline of a small letter on the oppositeface, and aseries of movable members which When properly assembledfollow the outline ofthe letters produced on the two faces of the block,the said members being pivoted to the block` enabling them to be broughtto position to Conform to the outline of' the letters on the block or tobe carried away from the said outline to a certain extent.

In testimony whereof I have signed my name to this speeifioation in thepresence of two subscribing Witnesses.
